neovim-go-nix-develop VS neovim-lua

https://github.com/jamespwilliams/neovim-go-nix-develop is a minimal Go neovim dev env I put together a while back (it can be created in one command with Nix, but even if you don’t use/know about Nix, you can read the file and see the config used).

The above is my attempt to create a minimal Neovim configuration that uses treesitter and nvim-lsp (albeit only for Go).

It uses Nix, so if you have Nix installed you can immediately try the configuration out in a self-contained development shell.

It’s too minimal for everyday use, but could be of inspiration.

I've updated it to use 1.18: https://github.com/jamespwilliams/neovim-go-nix-develop/commit/6e6e980752bbe50f9eea17dd438729aabfa7ef65

I used this as a starting point: https://github.com/brainfucksec/neovim-lua/blob/main/nvim/lua/core/options.lua, but remove matchit from the table.

I'm not a lua expert, so prior, I simply grabbed one off GitHub, and made a few changes. It's been okay, but does not support LSP for Java or Kotlin. And doesn't use fzf (telescope?).

Disclaimer: It may appear that I know what the hell I am doing with lua, but I do not. I am using a lua configuration from here: https://github.com/brainfucksec/neovim-lua. I am appending the above to his options.lua and am copying his append example from above in the same file.

neovim-lua

What I ended up starting with that worked out of the box was brainfucksec’s kiss setup

Rather than NvChad, I think this might be a better place to start since it includes only those you need This playlist was very helpful: https://www.youtube.com/watch?v=ctH-a-1eUME&list=PLhoH5vyxr6Qq41NFL4GvhFp-WLd5xzIzZ

https://github.com/brainfucksec/neovim-lua I found this one pretty simple, still all the basics are covered.
